Smarty在变量之间(在循环中)打印白色空格吗?
问题描述：
从PHP分配:
$smarty->assign("myArrays", Array(
Array( "title" => "ABC", "whatever" => 45),
Array( "title" => "DEF", "whatever" => 78)
));
在Smarty(v3.1.16).tpl文件中:
In Smarty (v3.1.16) .tpl file:
{assign "seperator" "|"}
{foreach from=$myArrays item=currentItem}
{$seperator}{$currentItem.title}{$seperator}
{/foreach}
然后它将输出为:
|ABC| |DEF|
.. 中间有一个空格" .
而且我认为这只是在这样的循环中.
.. WITH A "SPACE" in-between.
And i think it is only in such LOOPS.
为什么会这样?
以及如何解决呢?
Why is so?
And how to solve it please?
答
在循环中不使用空格:
{foreach from=$myArrays item=currentItem}{$seperator}{$currentItem.title}{$seperator}{/foreach}
或使用smarty指令巧妙地删除空格: {strip}/{strip} :
or use the smarty directive to make smarty remove spaces: {strip}/{strip}:
{strip}
{foreach from=$myArrays item=currentItem}
{$seperator}{$currentItem.title}{$seperator}{/foreach}
{/foreach}
{/strip}
